This free two-day festival features a line-up of local and celebrity chefs and food writers who demystify ingredients and issues behind our favorite foods—all designed to change the way we eat, buy, sell and talk about food. The event also features kid-friendly cooking demos and workshops, gardening activities with Green City Growers, a food trivia wheel with the Boston Collaborative for Food and Fitness, and other fun ways to get kids excited about good food as well as healthy food sampling from top brands. Former White House Pastry Chef, Bill Yosses; Tony Maws, Craigie On Main and Kirkland Tap and Trotter; Jody Adams, Rialto and Trade; Mary Dumont, Harvest Restaurant; Eric Brennan, Post 390; and Matt Jennings, Townsman will all be live on the main stage throughout the weekend.
